Brake line wall thickness

[01somta]

I went to a local auto parts store and pickup up a 6ft stick of 3/16" SS brake line for my rear axle line. Today I called another place about getting a longer stick (15-20ft) for th MC to rear axle, I called them because the auto parts store longest length was 6ft and I wanted to eliminate any extra splices that weren't manditory. I got the specs on the 15-20ft stick and it has a wall thickness of .035", so I then called the auto parts store and their line that I bent and flared for the rear was only .028" wall thickness. Obviously the thicker the better, but is .028" ok to leave for the rear and do the MC to rear in .035" or redo the rear line also? The entire rear line will also be covered in gravel guard if that makes any difference in protection.

Thanks Dustin

Having plumbed my car in SS, I used .025 or .028 wall 3/16 brake lines. It is still tough to flare. .035 would seem to make it that much tougher.....For what it is worth, I got mine at a shop that specializes in tubing. It was a tube bending shop. Jegs sells it, but it is coiled.....

So the .028 would be ok to keep on the rear and just do the rest in .035, I dont think the .028 is hard to flare at all.

Make sure the tubing you got is seamless. If not, don't use it. You will have leak issues.

When you say seamless, do you mean having a visuable seam running down the length of the tube?

Musclerodz is correct. and yes, seamless means no visible seam!

You must have a better flaring tool than I do! You have leak tested your flares...right?

No I have not leak tested anything yet, I still have to finish the lines. If they do leak then I will just take them to our local tube/hose store and have them duplicate and hydraulic flare them.

I have thought about your first question and not sure I can come up with the correct answer. Same size tubing (ID) and smaller OD due to increased wall size....It might increase peddle pressure...Let me do some more research....I guess if you have extra, I would re-do the rear end in the same size and OD tubing.....Make sure to plumb in a bias adjuster.

Just an FYI, McMaster Carr is a good place to get seamless tubing. Their prices are relatively cheap.

Are you looking for a AN flare or standard "brake line"double collar flare ?
